IT Administrator
About Me
I am a Computer Science graduate with over 7 years of hands-on experience in IT infrastructure, systems administration, and technical support. Throughout my career, I have worked in both small-business and freelance environments, honing my skills in Windows Server administration, networking, virtualization, scripting, and troubleshooting complex hardware and software issues. I am confident in my ability to serve as the sole technical escalation point, maintaining uptime under pressure and implementing cost-effective solutions that improve efficiency and business continuity.
My expertise includes managing Windows Server environments, Active Directory, LAN/WAN setup, virtualization technologies, VPNs, and PXE booting systems. I am proficient in troubleshooting and support tasks such as PC repair, backup and recovery, IT asset management, and remote support using tools like AnyDesk. Additionally, I am skilled in batch scripting, MS Office, Google Workspace, and technical documentation.
I have experience managing IT infrastructure for internet cafes, supporting 40 to 50 concurrent users across multiple branches. I have configured NIC teaming to enhance network performance and redundancy, built and maintained LAN infrastructure, and automated software deployment processes to reduce manual effort and minimize patch issues. I am also familiar with IT procurement and lifecycle planning, balancing budget constraints with performance requirements.
As a freelance IT support specialist, I provide remote and on-site technical assistance to small businesses and individuals, focusing on system optimization, OS deployments, and recommending cost-efficient infrastructure improvements. I am flexible to work night shifts and have effective communication skills in English for both technical and customer support contexts.
Currently, I am pursuing my Bachelor's Degree in Computer Science at Immaculada Concepcion College, with prior education in the ICT strand at ABE International Business College. I also hold a TESDA certification in Computer Systems Servicing NC II. I am eager to leverage my skills and experience to contribute to a dynamic IT team and continue growing professionally.
